XPO credits much of its success to keeping pace with the explosion of online shopping and other online business transactions. Retail and e-commerce deliveries — more than 35,000 every day — make up a quarter of the company’s revenue.

In the New York City metropolitan area alone, XPO couriers make 7,000 deliveries a day.

XPO ranked No. 8 on Forbes’ list of Growth Champions, following businesses in the United Arab Emirates, China, South Korea and Saudi Arabia.

The next American company, a New York-based investment trust, came in at No. 13.

To create the list, Forbes partnered with Statista to measure the revenue growth of the world’s 2,000 largest companies — known as the Forbes 2017 Global 2000. XPO ranked No. 1,603 on that list, which measures not only sales but market value, profits and assets.
